To all whom it may concern:

Be it known that if, CHAnLns Wnmnrrn, a citizen of the United States,residing at New York, in the county of New York and f'ltate of New York,have invented new and useful Improvements in SllOCk-iiLbSOl'bGl'S, ofwhich the following is a specification.

This invzition relates to improvements in automobile shock absorbers andhas for its principal object, the provision of a device 01 thischaracter which will include a spring tensioning mechanism whereinprovision is made for an initial internal adjustment and for a secondexternal adjustment whereby the spring may be made to properly supportthe load according to variations therein from time to time. Thetensioning mechanism is also designed to permit the structure to be usedupon light or heavy cars.

A. still further object of the invention resides in the provision of ashock absorber consisting of relatively separable elements which may beexpeditiously assembled or disassembled as the occasion demands; one inwhich the mating parts thereof can be operatively related with oneanother without threading the parts, and one in which said parts will beof a simple, strong and durable design.

A still further object of the invention resides in the provision of ashock absorber consisting of companion casings supporting cushioningsprings, hangers th ereior and tensioning mechanism including externaladjusting elements and means for holding said external elements againstcasual derangement from their adjusted positions.

Another object of the inventicm. resides in the provision of a shockabsorber consisting of a hanger bolt and shackle bolt and means forlubricating said parts while the device is 1n use. 1

With the above and other objects in view which will appear as the natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangements of parts which will hereinafter bemore fully described and particularly pointed out in the claims.

In the accompan "'ig drawing has been illustrated, a single andpreferred form. of the invention, it being, howev r, understood. that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and modi- Specificaticnof Letters Eateut.

i c t be 2 is a button; plan view thcrco 1". l, 3 a view looking atright angles to the device in. Fig. 1.

Fig. l is a section taken of Fig.

The invention comprises two parallel casings 1-1, each having aremovable cap 2, at its upper end from which a vertical lug 3. rises.Each of these lugs is provided with a pair of parallel passages llalinedwith. the vertical branches oil? a shaped passage 5, in a relativelyseparable cap (5.

Located in each casing is a spring hanger and connecting element whichis in the form of a substantially inverted ll shaped bolt 7, the bight8, 01 which is extended over a bushing, 9, extended through the cap 6and embracing a shackle bolt 10. llhe parallel branches ill-11, of thehanger extend through the mentioned passages l-l, and then into thecasing, the terminals thereof having threads 12, to accommodateadjusting nuts 18. These nuts are located beneath a follower l l. Atraveling nut or runner 15, is located in the casing, the branches 1111,being freely extended therethrough and interposed between the nut andthe follower 14:, is a cushioning spring 16. The follower 14, and thenuts 13, form. an eXter nal. adjusting mechanism wheieby the spring canbe initially adjusted and tensioned.

The two casings 11 are closed at their lower ends by a single cap 17,and extending through said cap in line withv the casings 1-1, areadjusting bolts 18, which form external tensioning means for the springson the line ll,

v within said casings. These bolts are threadedly connected in the nuts15 and are freely movable in the lower head 17, and exteriorly of saidhead they are formed with beads 19. Incident to the many vibrationswhich are transmitted to the structure in use, the bolts 18, tend tovibrate and come loose from their adjusted positions. I therefore wishto "use, in combination with. the heads 19, a, locking strap or plate20, which is interposed between the heads and detach ably connected withthe heads 17, by means of. a screw 21. The plate 20, has a lengthapproximately equal to the distance between the heads 19, and the endsof the plate are provided with angularly disposed surfaces 22, which areadapted to come in mutual engagement with the adjacent flat surfaces ofsaid heads 19. This holds the bolts 18, against retrograde rotation.

The bushing 9, extends through both caps 6, of the structure, andlocated beneath said bushing is a second bushing 23, which also extendsinto the lugs A bolt 2%, is passed through the second bushing s3, andthrough said lugs The bolts 10 and 2%, are pro- YlClGtl with removablelubricating cups 25, by means of which a lubricant may be distributed inand around the bushings, causing the parts to work free at all times.

From the description set forth, it will be observed that the device issimple, strong and durable, consisting of comparatively few parts, allof which being so designed where'- by they may be readily assembled ordisassembled as the occasion necessitates. l he cushioning springs maybe tensioned initially and after the casings 1 are applied and the bolts18 connected with the nuts or runners 15, any further tension of thesprings can be had by simply adjusting said bolts from the outside ofthe structure. When the final adjustment of the springs is had, thelocking plate or strap 20, is applied in the manner hereinbe'l ore setforth, causing the bolts to be positively locked against retro graderotation.

lVhat is claimed as new is l. A shock absorber embodying a cap having anupstanding lug, a second cap superimposed upon said lug, a U-shapedhanger having the bight portion thereof held within said second cap andthe branches thereof slidable through the first named cap and its lug, afollower adjustable longitudinally of said branches, a runner slidableon said branches and formed with openings, through which said branchesextend, a spring interposed between said follower and said runner, and aspring tensioning bolt passing through said follower and having athreaded engagement with said runner.

2. A shock absorber, comprising a pair of casings each ha ing a lug anda cap m vable relatively thereto, means connecting the cap ot one casingwith the cap of the other casing, means connecting the lug of one easingwith the lug of the other casing, U- shaped hangers passing through saidlugs and caps and over said first means, runners embracing and slidablymounted upon the branches of said hangers within the casings, followerslocated within the casings and adjustably mounted upon the branches ofsaid hangers, springs interposed between the followers and said runners,and adjusting bolts passing into the casings and having a threadedengagement with said runners.

In testimony whereof I aflix my signature in presence of two witnesses.
